Comparing megapixels has fallen out of fashion for the most part, at least when it comes to smartphone cameras. In fact, the iPhone XR camera boasts just 12 megapixels, and every version up to and including the iPhone 6 had just 8 megapixels. Now, however, Samsung and Xiaomi have teamed up to build a 108-megapixel sensor destined to fit inside of a future smartphone. It's the first commercial chip of its kind to break the century mark in terms of resolution. And while it's an impressive feat, you probably shouldn't expect it to work just like its 100-megapixel competition which typically costs as much as a decent SUV.
